This document describes a laboratory test method to determine the susceptibility of thermal insulation products used for construction against mould growth under specified climatic conditions.
The method is applicable to both factory-made products and in situ formed products. Factory-made products include panels, mats and rolls.
NOTE In situ formed products are usually those that are delivered loose and installed by blowing-in, pouring, or spraying-on, eventually using water and/or binder, whether or not they are also treated using additives.
The test is carried out with one of the conditions described in Table 1.
This test method determines the susceptibility of a thermal insulation material to mould growth, but it does not determine the suitability for use in a given design (wall, roof, etc.).
This method does not predict the resistance of an insulation product to water damage.
